Flaky test in windows GPU CI

[azai91]

In the windows-GPU stage of the CI, different test_random tests fail.

test_random.test_exponential_generator fails on commit 6a293fc but passes after updating README
#13595
http://jenkins.mxnet-ci.amazon-ml.com/blue/organizations/jenkins/mxnet-validation%2Fwindows-gpu/detail/PR-13595/9/pipeline

test_random.test_uniform_generator
http://jenkins.mxnet-ci.amazon-ml.com/blue/organizations/jenkins/mxnet-validation%2Fwindows-gpu/detail/PR-13681/37/pipeline

Seems to only occur on windows GPU build.

Another test which failed on Windows GPU :
test_operator_gpu.test_multinomial_generator

The failure is here on Jenkins : http://jenkins.mxnet-ci.amazon-ml.com/blue/organizations/jenkins/mxnet-validation%2Fwindows-gpu/detail/PR-13678/24/pipeline

Like @azai91 mentioned, the failure happens on Windows GPU only and is flaky in nature.
